Summary: Firstly getting this lens was a bit of a hassle. The lens was available at a very competitive price from Amazon, but the adaptor (also available at a VERY competitive price on Amazon) could not be posted to my address (reasons not understood).
Summary: The lens was made by the manufacturer for the camera. It is a perfect fit and works very nicely. Gee, I wonder why? Well it was made by the people that made the camera and it was made for the camera. I can get some very close photos with this lens without crowding the subject and blocking the light.
Summary: This was my 1st purchase, the lens showed the segments of the tile in my kitchen, which are impossible to see. Its 0.7X magnification is but would like the Raynox MSN 202 (5.5 X magnification) or MSN 505 (8.8 X magnification) which are much more powerful, for a similar price.
Summary: I have a clip on macro lens from Raynox, but wanted to check out the DMW-LC55 which is made for Panasonic cameras. The lens arrived soon after I placed the order, and so far has met my expectations.
Summary: Finally i got the lens. The review of the other reviewer is misleading. The magnifictication increase you can get is mind blowing. Instead of the closest shooting distance of 1.00m of the Panasonic FZ7's standard macro zoom position (432mm) you can now get as close as 33 cm with this lens.
Summary: This lens is fairly inexpensive and the reason for that is while it definitely lets you get really close and the image is definitely larger than without it, the fact is the FZ7 and the FZ30 macro settings are already so good that the image is perhaps 15% or so bigger than without it.
